ENGLISH: Strong coastal upwelling occurs in the Gulf of Panama regularly each year during the season, from about January through April, when strong northerly winds are blowing offshore. Because of the evident importance of upwelling to the ecology of the Gulf of Panama, we commenced in the fall of 1954 a study of various physical, chemical, and biological phenomena associated therewith. Observations were taken at bi-weekly intervals at a fixed location in the Gulf (approximately 10 miles SE of Taboga Island) to supplement the serial observations of sea level, sea temperature, and winds that have been gathered for many years by the Panama Canal Company. SPANISH: Cado año, en la estación de enero a abril, cuando los vientos del nortesoplan vigorosamente frente a la costa, ocurre en el Golfo de Panamá un fuerte afloramiento costanero. Se cree que este afloramiento periódico en el Golfo de Panamá es responsable de la alta productividad biológica que sostiene considerables cantidades de organismos de importancia comercial. Esta región, por ejemplo, es una fuente importante de la especie Cetengraulis mysticetus) pez de carnada para el atún, (Alverson y Shimada, 1957) y mantiene una considerable pesca de camarones llamados langostinos (Burkenroad, Obarrio y Mendoza,1955).(PDF contains 54 pages.)
